PEG/PPG dimethicone structure and function
April dimethiconestructure and functionPEG/PPG dimethicone compounds shouldbe used in instances where they providebenefits that cannot be obtained by organiccompounds. These properties include: Lowering of surface tension (into therange of 25 dynes/cm). Provide unique skin feel. Provide unique emulsification properties(especially in invert emulsions). Provide film formation. Provide foaming of properties are a direct result of thestructure, but the structure needs to becarefully selected. PEG/PPG dimethiconepolymers have increased polarity, by virtueof their polyoxyalkylene groups. It isimportant to note that these modificationsare done by chemical reaction between a reactive silicone and a vinyl containingcompound.
